Now at version 1.6, LEGO Digital Designer is quite simply the best virtual building system out there – with its “Click-Stick” method of 3D modeling winning praise from children, parents, teachers and design enthusiasts everywhere.

I had problems getting this to run on my PowerBook (G4, OS 10.3.9) until I emailed their support for help. This is what they told me to try, and now it works without any problems!...

The Qube Software engine relies on the Creative OpenAL audio library, which is included with Mac OS X 10.4 but not 10.3.9.
If you're using 10.3.9 you must first download and install OpenAL, available from <http://developer.creative.com/articles/article.asp?cat=1&sbcat=31&top=38&aid=97>.
